There are "taupe" colors out there that may match the cream base color & I would go that route myself. As for the glue I have used the water based glues & they work but require too much cure time for my liking. Outdoor type rubber contact cement is what we used, we pre-fit the carpet, rolled back a couple feet sprayed the floor & backside of the carpet, waited 2 min & pressed her down. The same can be done with a brush.
